Abstract
The invention discloses a kind of ship metal surface mordant, it is characterised in that；Its component consists of the following composition by weight percentage：0.8mol/L 45 parts of dilute sulfuric acid or watery hydrochloric acid, 2.9 parts of thiosemicarbazides, 14 parts of carboxycellulose salt, 12 parts of Rosin Amine Polyoxyethylene Ether ether, 10 parts of OP surfactants, 30 parts of BTA, 14 parts of imidazoline, 7 parts of KI.After the product prepared in the present invention removes the oxidation iron rust of metal surface; by diluted acid further with base steel precursor reactant; in order to prevent diluted acid excessive corrosion metal; using carboxycellulose salt, Rosin Amine Polyoxyethylene Ether ether, OP surfactants and BTA; change the cathode reaction of corrosion electrochemistry process or the activation energy of anode reaction; so as to cloudy stagnant cathode and anode reaction, sealing protection film is formed to its steel surface by thiosemicarbazides, imidazoline and KI.
Description
Technical field
The present invention relates to a kind of metal protector, and in particular to a kind of ship metal surface mordant and preparation method thereof.
Background technology
Metal and seawater occur electrochemical reaction and are lost and go bad.The electrochemical corrosion of metal is due to metal in seawater
Caused by the electrochemical nonuniformity on surface.This inhomogeneities can be by metal (such as crystal boundary, be mingled with) or metal watch in itself
The change (such as oxygen concentration difference etc.) of medium on the different parts of face and produce.Carbon steel is most widely used in exploitation marine resources facility
Structural material.People carried out research in considerable detail to the corrosion behavior of carbon steel in the seawater.Extensive hanging test table
Bright, the average corrosion rate of carbon steel in the seawater is 0.05-0.13 millimeters/year, and pitting corrosion speed is up to average annual corrosion rate
10 times.The principal element for influenceing steel corrosion rate in the seawater is the feed speed to steel surface oxygen, in addition with temperature, stream
Speed, fouling organism, calcium carbonate dirt, pollution and the welding of steel construction, stress etc., and the influence factor of corrosion rate.So
There is an urgent need to have a kind of metal surface mordant to alleviate corrosion phenomenon in market.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of pickling of ship metal surface
Agent.
Present invention also offers the preparation method of above-mentioned mordant.
Technical scheme：To achieve the above object, the present invention provides a kind of ship metal surface mordant, and its component is by weight
Percentage consists of the following composition：0.8mol/L 48 parts of dilute sulfuric acid or watery hydrochloric acid, 3.2 parts of thiosemicarbazides, carboxycellulose
15 parts of salt, 12 parts of Rosin Amine Polyoxyethylene Ether ether, 15 parts of OP surfactants, 35 parts of BTA, 15 parts of imidazoline, KI
9 parts.
Further, the carboxycellulose salt include one kind either in carboxycellulose potassium of carboxycellulose sodium or
Two kinds.
A kind of preparation method of above-mentioned ship metal surface mordant, it is characterised in that：The preparation method includes as follows
Step：
(1) raw material components are weighed according to the ingredients weight parts described in claim 1；
(2) by above-mentioned raw materials put in a kettle heat mixture it is uniform, be heated to 158 DEG C of 30~60min of high-speed stirred i.e.
Can.
Beneficial effect：The present invention has the advantage that for conventional art：
It is further anti-with steel matrix by diluted acid after the product prepared in the present invention removes the oxidation iron rust of metal surface
Should, in order to prevent diluted acid excessive corrosion metal, using carboxycellulose salt, Rosin Amine Polyoxyethylene Ether ether, OP surfactants and
BTA, change the cathode reaction of corrosion electrochemistry process or the activation energy of anode reaction, so as to which cloudy stagnant cathode and anode is anti-
Should, sealing protection film is formed to its steel surface by thiosemicarbazides, imidazoline and KI.
Embodiment
The present invention is further described with reference to embodiment.
A kind of ship metal surface mordant, its component consist of the following composition by weight percentage：0.8mol/L's is dilute
48 parts of sulfuric acid or watery hydrochloric acid, 3.2 parts of thiosemicarbazides, 15 parts of carboxycellulose salt, 12 parts of Rosin Amine Polyoxyethylene Ether ether, OP surfaces
15 parts of activating agent, 35 parts of BTA, 15 parts of imidazoline, 9 parts of KI.
A kind of preparation method of above-mentioned ship metal surface mordant, the preparation method comprise the following steps：
(1) raw material components are weighed according to the ingredients weight parts described in claim 1；
(2) by above-mentioned raw materials put in a kettle heat mixture it is uniform, be heated to 158 DEG C of high-speed stirred 60min.
After the product prepared by embodiment, it can effectively clean and suppress unwanted corrosion in metal, and after being formed
Phase protects.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：Come for those skilled in the art
Say, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should be regarded as
Protection scope of the present invention.
